Casio to Release First G-SHOCK 5000 Series Watch with Full Metal Construction, Capturing the Heritage of the Very First G-SHOCK


Basel, March 21, 2018 — Casio Computer Co., Ltd., announced today the release of a new addition to the G-SHOCK brand of shock-resistant watches. The GMW-B5000 is the first watch with full metal construction in the iconic square-shaped 5000 series.

Since the release of the DW-5000C, which was the very first G-SHOCK released in 1983, the 5000 series has stayed true to the square-shaped pedigree of that very first G-SHOCK. It has proven popular with many people as a series that symbolizes the G-SHOCK brand.

The new GMW-B5000 nods to the heritage of that first-ever G-SHOCK while pushing new boundaries in every way—from its materials to the construction and features. The outer components, including the watch band, case, and bezel, are entirely made from stainless steel. The watch also employs a new shock-resistant construction made possible by the use of a highly durable fine resin insert between the stainless steel case and bezel to absorb shock.

In terms of features, the watch keeps accurate time anywhere in the world using the Connected Engine, which connects to a time server via a paired smartphone, and radio wave time-calibration signals. The watch connects to the G-SHOCK Connected smartphone app to enable the user to look up instructions for operating the watch and easily change settings such as world time and alarms from the app.

The GMW-B5000TFG-9 is a special edition watch created to mark the 35th anniversary of G-SHOCK, with a gold ion plating treatment and the G-SHOCK 35th anniversary logo inscribed on the back case, and it comes in a commemorative package.

The GMW-B5000TFC-1 is a special model developed in collaboration with leading Japanese luggage-maker Yoshida & Co., Ltd. A limited edition of just 500 watches will be released worldwide. This model comes cased in a specially designed bag produced by Yoshida & Co., Ltd., under its PORTER brand. The GMW-B5000TFC-1 features a diamond-like carbon (DLC) coating throughout and is inscribed with the G-SHOCK 35th anniversary logo on the case back.
